Takes a Movie Graph format string (in the form of {token}), a list of parameters (which normally come from the runningUMovieGraphPipeline) and resolves them into a string. Unknown tokens are ignored. Which tokens can be resolved depends on the contents of InParams, tokens from settings rely on a evaluated config being provided, etc.
